You should be able to get most of those individual pieces at any place that sells car audio hardware. I don't know if you have a Fry's Electronics or Best Buy around you, but even Circuit City will sell that stuff. I believe that Spade Terminals are like 1 or 2 bucks for the pair as are Ring terminals. Fuse Holders might be a little more. Just make sure you get the waterproof ones. It's the cylinder style one. You could even get some of the terminals at Radio Shack, like the ring ones where you ground and connect to the battery. At this level, it's not totally mandatory to get gold if you don't want. It's mostly used just because it has a bit of a higher tolerance to road conditions, and gold is a tiny bit more malleable, so theoretically, it'd offer a slightly better connection. But when just connecting to the battery, I think it's splitting hairs for most people. If you still can't find a fuseholder that fits your budget, let me know.
